I wrote the following sentence:
We will proceed with the registration after the remaining balance is settled.
Somehow, I find that using the word settled in this sentence sounds a bit rude. This is especially true if we consider that I'm offering something in my previous sentence. I don't want to sound too demanding or make the reader feel bound to do anything.
I was thinking to replace settled with made. But still, made doesn't sound the best possible word.
What are the expressions that could be used in a sentence like this to say that an amount is to be paid and still sound gentle?
